SPECIFICATION arming part of Letters Patent No. 588,978, date AApplication ned December 19,1896. serai No. 616,302. (No man.)

T0 all whom, itmay concern: Y 'Be it known that I, WILLIAM GORDON, ofBoston, inl the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in Machines for IndentingBootor yShoe Soles, of which the following is a specification. l, 1

' This invention has Aforgits. object toprovide a machine adapted toform a series' of grooves or indentations in a boot or shoe sole for thepurpose of corrugating its tread-surface and thus adapting it to resistslipping, or for the purpose of increasing Athe rlexibilityrof the sole,my invention having inrview the formation of grooves or indentationswithout the removal of any of the material of the sole.

My invention consists in the improvements which I will now proceed todescribe and claim.

In the accompanying drawings, Figure l represents a top plan view ofamachine embodying my invention. Fig. 2 represents a front elevation ofthe same. Fig. 3 represents a section on line 3 3 of Fig. 2. Fig. 4represents a section on line 4 4 of Fig. l. Fig.

g 5 represents a section on line 5 5 of Fig. l.

Fig. 6 represents a section on line 6 6 of Fig.

l 1. -Fig '7 represents a view similar to Fig. 6,

showing the grooving or indenting diein a different position. Fig. 8represents a plan View of the grooving-die, detached. Fig. 9 representsa section on line 9 9, Fig. kS. Fig.

10 represents a view of a sole grooved or indented by myimprovedmachine. Fig. ll represents a section on line 1l 1l, Fig. 10. Fig. 12represents a perspective view of a portion of the machine.

In the drawings, in which the same letters or igures designate the sameparts or features,

a represents the supporting-frame of the ma--` chine, the same having ahorizontal bed or table portion a. Y i

b represents a shaft which is vjournaled in bearings Von the 4frame aand having enlargements o,constitutin g bed-rolls or bed-roll sectionsarranged to support asole c, that passes from the'inner end of the bedor table a', the upper surface of said sections o being substantiallyiiush with the upper surface of the bed a.

ugust 31, 1897.

d represents a shaft or holder which is journaled in bearings in theframe a above the shaft b, and is provided with a fiat seat or face d',to which is detachably secured, by bolts or screws e', a grooving-diee', the back or inner surfaceof which is fiat and is formed to fit theseat d', while its outer face is convex and provided with ribs 2 2,formed to make grooves or indentations 3V 3, Figs. 10 and 11in one sideof the sole c, which is passed between the die c and the bedroll b.

The die eis provided with iianges 'e2 e2, having slots c3 c3, whichreceive the attachingscrews e', said slots and screws permitting theVdie to be adj usted longitudinally. The shafts b and d are positivelyrotated-by suitable gearing, which may be arranged as shown in thedrawings or in any other suitable way, to rotate the said shafts andtheir attachmentsin the direction indicated by the arrows in Figs. 3 and4.

A slide or carrier is provided to grasp the sole c and presenty itatt-he proper time to the die e and the cooperating bed-roll section bto cause the dies to indent the sole, as indicated in FigQlO. The saidslide or carrier, as here shown, comprises a frame composed of two sidebars, each made up of two members g g', Fig. 12, a front cross-bar g2,connecting said side bars g g atthe front of the machine, and a rearcross-bar (3, connecting said side bars at-the rear of the machine. i

The members g of the side bars are fitted to slide in guides g4 in thebed or table a', and are provided with upwardly-projecting lugs gG,which are engaged by camsh, affixed to the shaft d, said cams bytheirengagement with the lugs g( causing the feed frame or carriertovmove forward in the direction indicated by the arrow in Fig. l2. Tothe feed slide or carrier are connected two pairs of jaws i t', adaptedto hold'the end portion of a sole, as indicated in Fig. l, said jawsbeing yieldingly connected with the feed slide or carrier by means of 'arod i2, which slidesl lengthwise in guides 6, adj ustably mounted on thefront cross-bar g2, and springs't, interposed between the guides 116 andshoulders on the rod 2, said springs enabling the jaws t' t" to yieldtoward the front cross-bar g2.

The rods [2 are provided with right and left hand screwethreads i* andi5, which are engaged with correspondingly-th read ed orifices in thejaws i" and t', so that when the rods t2 are turned they adjust the jawst' i' simultaneously toward and from each other, thus adapting them tosoles of different widths.

The guides t" are adjustable toward and from cach other on the cross-barg2, and are held at any desired adjustment by means of set-screws 7, sothat the jaws can be adapted to any length of sole.

The feed slide or carrier is movable on the frame of the machine in adirection at right angles to the axes of the shafts l) and d, and isguided by fixed ears or guides jj, in which the members g of the sidebars are fitted to slide. The said feed-slide is moved in the directionrequired to carry a sole engaged with the jaws t' t" toward the meetingpoint of the indenting-die and corresponding bedroll by means of thecams 71., the latter engaging the ears g on the feed-slide, as shown inFig. 4. Vhen the cams pass over the ears gs, the feed-slide is releasedand is returned to its starting position by means of a spring 7n,attached at one end to the frame of the machine and at the other end toan arm 7c', affixed to the rear cross-bar g3.

m onr represent stops which limit the movement of the feed slide bymeans of the sprin g 7c.

The operation is as follows: After the feedslide has been returned bythe spring 7o to its starting position and before the cams 7L reach thelugs gf the operator engages a sole with the jaws i li'. lVhcn the camsengage the lugs g, the feed-slide is moved forward, carrying the solewith it and presenting the sole to the die e and the accompanyingbed-roll just as the die reaches the position to engage the advancingedge of the sole at a point within its margin. The cams continue toadvance the feed-slide and sole while the die is acting upon it, theresult being the formation of the grooves 3 3 in the sole, as shown inFigs. l0 and ll. After the die has completed its action the cams releasethe lugs g6 and the feedslide is returned to its starting position,which is determined by the stops m.

In opcratin g upon the soles which are formed as rights7 and lefts thedie for one form will be placed at one end of the seat d', while for theother form the die will be placed at the opposite en d of said seat,which, as shown in Fig. l, is made of suflicient length to re ceive twodies, the screw-holes d10 d10 (shown at the left-hand end of the seat inFig. l) indicating where the other die would be attached to the holder.

10 1110 represent ears or plates which are attachcd to the jaws t" toprevent the jaws from dropping onto the shaft b when they are moved overthe latter, said plates @'10 trailing after the jaws and remaining onthe table a.

The jaws 'i are at the same time supported by rods i12, attached to thejaws t" and having a sliding itin holes formed in the jaws if.
